Sahih al-Bukhari Book 9, Hadith 74
My father and I went to Abi Barza Al-Aslami and my father said to him, "Tell us how Allah's Messenger (ﷺ)
used to offer the compulsory congregational prayers." He said, "He used to pray the Zuhr prayer,
which you call the first prayer, as the sun declined at noon, the `Asr at a time when one of US could
go to his family at the farthest place in Medina while the sun was still hot. (The narrator forgot what
Abu Barza had said about the Maghrib prayer), and the Prophet (ﷺ) preferred to pray the `Isha' late and
disliked to sleep before it or talk after it. And he used to return after finishing the morning prayer at
such a time when it was possible for one to recognize the person sitting by his side and he (the
Prophet) used to recite 60 to 100 'Ayat' (verses) of the Qur'an in it."
`Umar came cursing the disbelievers (of Quraish) on the day of Al-Khandaq (the battle of Trench) and said, "I could not offer the `Asr prayer till the sun had set. Then we went to Buthan and he offered the (`Asr) prayer after sunset and then he offered the Maghrib prayer.
Once he waited for Al-Hasan and he did not show up till it was about the usual time for him to start his speech; then he came and apologized saying, "Our neighbors invited us." Then he added, "Narrated Anas, 'Once we waited for the Prophet (ﷺ) till it was midnight or about midnight. He came and led the prayer, and after finishing it, he addressed us and said, 'All the people prayed and then slept and you had been in prayer as long as you were waiting for it." Al-Hasan said, "The people are regarded as performing good deeds as long as they are waiting for doing good deeds." Al-Hasan's statement is a portion of Anas's Hadith from the Prophet (ﷺ) .
